Depends what kind of WHEA error it is. The most stable system on the planet will still log some sort of WHEA error, but some of them are directly related to unstable overclocks. Are you using HWInfo to track the WHEA errors? If so, then those are the critical ones that are symptoms of instability.
They can be related to CPU or memory instability, though.
